Studies emphasizing the physical, operational and economics characteristics of the fishing fleet were realized, focusing the fleet based in Central Amazon but with gaps about the characteristics in peripheral regions. In this sense the work aimed to analyze the necessary costs to entry of new vessel on activity and to provide information in relation to the costs of fishing expeditions and economic revenue of fishing activity. The study was realized in the Medium Madeira River region and collected information about maintenance, cost and income of fishing expeditions, from June 2003 until May 2004, using questionnaires applied to skippers and fishers of boats and motorized canoes. The gear it was most expensive item on acquisition and the fishers the financer. The fishing expeditions of vessels were financed by six agents, fishers and ice plant owner were the principal financers. Fuel was the main items of cost on fishing expeditions of boats, fuel and ice to motorized canoes. The skippers and owners of fishing boats had a clear gain of 0.6 and 0.5 living wages by fishing expeditions and the fishers 0.3 while fishers of motorized canoes had a clear gain of 0.5 living wages.
